Question

Phagocytosis was first seen by
A. Huxley
B. Strasburger
C. Haeckel
D. Metchnikoff

Answer 1

Hint:This person got a Nobel Prize in 1908 with Paul Ehrlich in Physiology or Medicine. He was a Russian zoologist.

Complete Answer:
Phagocytosis is the mechanism by which a cell uses its plasma membrane to absorb a large particle that leads to a phagosome. It is one type of endocytosis. Phagocytosis is an important process for eliminating pathogens and cell debris in the immune system of a multicellular organism. In the phagosome the intake content is then digested. Many of the examples of objects that can be phagocytized include bacteria, dead tissue cells and little mineral particles. Some protozoa use phagocytosis for nutrient input.
The English biologist and anthropologist Thomas Henry Huxley was an anatomist. For his advocacy of Charles Darwin's evolution theory, he is regarded as "Darwin's Bulldog."
The German plant cytologist was Strasburger. The stages of nuclear and cellular division in algae and higher plants are especially well known in Strasburger.
Haeckel was a German zoologist, naturalist, eugenicist, philosopher, physicist, professor, naval biologist and artist who found, defined and gave names to thousands of new species.
Metchnikoff was a Moldavian and Ukrainian imperial Russian zoologist most notable for his pioneering immunology studies. The discovery of phagocytes in 1882 was especially attributed to him.

Thus, the correct answer is option D. i.e., Metchnikoff.

Note: Phagocytosis is a key immune response mechanism. It is one of the originating branches and first infection reaction mechanisms of an adaptive immune response. While most cells are phagocytic capable, some cell types do so in their primary role.
